wnsnme mcnmn Application flledoctober so, 1923. Serial 110.371,?38. I

. My invention relates to washin machines of. the type in which the articles to ewashed, which may be castings or other metal parts, such as automobile fenders, running boards,

8 &c., or dishes, areymoved through the 'ma- 'chine, and between the points of their admission and discharge are washed by throwing the water, usually containing a cleansing agent in solution, forcibly against them. In no some machines of this type the articles to be washed are, continuously in motion while the washing is being done, and in others they are stationary at that time, and my present invention contemplates washing articles hanllfi dled in either way, although I have chosen to show it embodied in a machine in which the articles are moved continuously during-the.

washing moperation. The "improvements which form the subject-matter of this appliw cation have to do principally with the means for throwing the Wash water against the articles so that all parts thereof will be thorcleansed during" the transit of. the

* articles from the inlet to the outlet end of u the' machine The nature of my invention will'appear from the following description of the embodiment thereof illustrated in the accompanying drawings in connection with the claims hereinafter made.

In the drawings,-v a

Fig. 1 is a side elevation of my mproved mach1ne;- Q I Fig. 2 is a plan view thereof;-

Fig. 3'is a vertical cross-section, enlarged,

as on line 3-8 of Fig. 1; and v Fig. 4 is an enlarged central vertical section of one of the devices for throwing the water. i v v The machine illustrated comprises a boxso like structure preferably of sheet metal, the

lower portion of which is in the-form of a tank 5 adapted to contain wash water, or

where rinsing also is done rinsing water, in which case two tanks are provided suitably e5 separated so that the was water does not contaminate the rinsing water; An arrangement for'this pur ose is shown in the pendagplication-o George S. Blakeslee Seo. 243,673,-filed uly 6, 1918. The

ing. rial so tank 5 is supported. above the floor in any suitable way, as by legs 6, to provide-s ace below it for the return flight of the en less conveyor hereinafter described. Above the tank portion of the machine and extending es longitudinally at. opposite sides thereof are rails 7, 8, preferably in the form. of angle lron, which are adapted to form tracks to support and guide theupper flight of an end ess conveyor 9 on which the articles to be washed rest while they move through the machine. In the construction illustrated this conveyor comprises side chains 10, 11 connected by'cross. strips 12 set on edge and spaced :1. distance apart, as best shown in Fig. 2. The chains 10, 11 run. over upper sprocket wheels 13, 14 at the outlet end of the machineand sprocket wheels 15, 16 at the inlet end thereof, and under sprocket wheels 17 at the outlet .end of the machine and sprocket wheels 18 adjacent to the. inlet end of the machine, as shownin Fi 1. The

sprocket wheels 13, 14 are carried y ashaft 19, and the sprocket wheels 17 by a shaft 20, both of which are suitably .journaled in brackets secured to a frame-work 21 which pro ects at the opposite'ends of the machine,

as shown in Fig. 1. The sprocket wheels 15, 16 are n like manner carried by a shaft 22 7 sprocket wheels 18 serveas belt. tightenersand are used to regulate the tension of the conveyor. Below the tank 5 angle iron tracks 26, 27 are provided at op osite sides of the machine for supporting t 1e lower flight of the conveyor during its return movement, as best shown in Fi 3.

The conveyor is driven so thatit travels over the tank 5 by any suitable means, such a shaft 23- which is'mounted in adas a motor 28 and reduction gearing that is shown enclosed in a casing 29, a shaft of such gearing. having thereon a sprocket whic also carriesa sprocket wheel 34 connecte by a chain 35 to a sprocket wheel 36 Figs...1 and 2. By this construction the motor 28 operates to drive the shaft 19 and thereby operate the conveyor. While I pre- [wheel 30 connected by achain. 31 1to a sprocket wheel 32 carried by 'a shaft 33,

mounted onthe shaft 19, as best shown in fer. to employ the means described for this purpose it will beunderstood that any other suitable devicesmay be employed.

The means for throwing water upon the articles to be washed comprises a pumpv 37,

preferably of the centrifugal, type, and

' ends of these driven by a motor 38 disposed at one side of the machine, as shown in Figs. 1 and 2, the

armature shaft of the motor being directly connected to the pump by ashaft 39. The intake side of the pump is connected to the lower portion'of the tank 5 by a pipe 40' while the discharge side thereof is connected by a pipe 41 with a vertical header 42, the

. preferably provided, two below the conveyor 9 and two in an inverted position'in the upper portion of the washing compartment, as

best shown in Fig. 3. The number of these cas'tingsmay be varied to suit diiferent conditions, but ordinarily the arrangement shown will give very satisfactory results. The construction of these castings is best shown in Fig. 4, from which it will be seen that there is a hollow base portion 48 supported on legs 49, an intermediate port on 50 resting on and bolted to the base portion 48 and provided witha central bearing member .51, and an inlet passage 52 formed in a laterally-disposed arm 53 adapted to be connected with one of the branch pipes 45, 46. The passage 52 opens upwardly at the upper end of the intermediate member 50 into --a hollow rotatable head 54 preferably somewhat of a mushroom shape.

which is provided with a number of perforations in its outer and lateral surfaces is provided with a circular opening at its un- I derside adapted to receive the upper end of the intermediate member 50 and fit fairly closely thereon but not closely enough to 1nterfere with the free rotation of said head.

- The head is provided at its center with a I are provided between per end vertically-disposed hub 55 by means of which it is fitted upon'and keyed to the upof, a shaft or spindle 56 journaled in the bearing member 51 and having its lower end fitted in a bearing 57 in the bottom of. the base member 48, as best shown in Fig, 4. Mounted upon the. lower portion of the spindle 56 and non-rotatably connected therewith, preferably by a pin 58, is a worm wheel 59, and preferably ball bearings the under side of said worm wheel and the base member 48 to take the downward thrust. The worm wheel 59 meshes with a worm 61 carried by a shaft 62 which projects into the base member 48,

and at its outer end carries a, double pulley machine in connection with the overhead b This head,

5 and be-supplied under considerable pressure to the water throwing devices above and below the path of the articles to be washed. The water will enter each of said water throwing devices through the passage 52 thereof and be delivered to its head 54 in a direction parallel with the axis of the head,

so that the water will impinge directly against the head, and will be discharged through the perforations 69 therein. Meanwhile, the heads 54 will be rotated by-the operation'of the motor 64, which operates to rotate the spindles 56 through the worm 61 and worm water discharged through the perforations 69 will be discharged forcibly in a multiplicity of directions, and, therefore, will be directed against all parts of the articles being washed. This feature of positively rotating the head or heads 54 while thewater is being discharged through them is a very gear 59. Consequently, the

important part of my invention, since it inv sures the violent application of the water to all parts of the, articles without the loss of force which is experienced in machines which I spraying device, as in such machines a considerable part of the force of the water is absorbed in effecting the rotation of the head, and in machines of the type under consideration the force with which the water is applied to the articles vitally affects the success of the washing operation; By rotating the head or heads while washing is being done the water is properly distributed so that the articles are thoroughly washed all overinstead of along certain lines only as would be the case if the heads did not rotate. The improvements described, therefore, make practicable the use of pressure make use-of the reactionary force of v the discharged waterto eflectrotation of a heads of the spray or jet type for washing I articles which heretofore could be successfully washedonly by machines of the paddle wheel type. The construction by which the revolving heads are rotated comparatively slowly provides for directing relatively solid streams of water against the articles for securing maximum 1m acting energy of the washwater against t em, since the velocity of the .water andits impacting energy are not impaired as would be the case if the revolving heads were rotated at fair] speed, which would tend to nebulize the water and destroy the directional characteristic of the nozzle openings in said heads. It will be understood, of course, that the wash waterfalls back into the tank and may e used over and over again, and that it is high i heated in any suitable way, as by steampipes such as are commonly used in washing machines.

While my invention may best be embodied in a washing machine-in which the articles through the machine, but remain in a'sta-- tionary position while being washed. S

far as I am aware, I am the first inthe art to devise a washing machine in whichthe water usedfor washing purposes is forcibly projected against the articles to be, washed by means of a rotating distributing head through which the water is forced, and which is caused to rotate by power driven means apart from or independent of the pressure of the water supplied to and distributed bysuch head. The claims hereinafter madeare therefore to be construed accordingly. Y What I claim as my invention and desire to secure by Letters. Patent, is-

1. In a: washing machine, the combination with a washing compartment having means therein for supporting the articles to be washed, of water distributing-members arranged oppositely to each other, respectively.

above and below said supporting means,

from,

each-of said distributing members comprising a stationary base having a water pas-' sage therein, a rotating head revolubly supported by said base and communicating with said water passage, said. head having perforations for the discharge of water thereand means mounted on the base operable to rotate said head, and means for supplying water to the water passages of said distributing members.

2. A water distributing device comprising a hollow base, an intermediate member mounted on and secured to said base, said intermediate member having a water passage therein, a .shafi jpurnaled in said intermediate member, a perforated head mounted on and rotating with said shaft, saidhead communicating with said water passage, and means in the base for rotating said shaft.

- 3-. A water distributing device comprising a hollow base, an intermediate member mounted on and secured to said base, said intermediate member having a water passage therein, a shaft journaled in said inter-. mediate member and in said base, a perforated head mounted on and rotating "with said. shaft, said head communicating with said water passage, and a worm and worm wheel in said base for rotating said shaft.
